Method for determining the values of parameters

1. A method for determining values of parameters for a controller of a vehicle, the method comprising:

providing a plurality of sets of values to a vehicle controller of the vehicle, wherein each set of values has a number of values of the parameters, wherein the sets of values are allocated to vehicle dynamic models of different body types of vehicles produced by a vehicle manufacturer, the parameters are indicative of physical characteristics of the different body types of the vehicles produced by the vehicle manufacturer;

driving a test route with the vehicle, and recording, by the vehicle controller, a number of operating variables of the vehicle in the process;

calculating, by the vehicle controller, a plurality of error measures as a function of the parameters and the operating variables, wherein each error measure is calculated using the values of a respective set of values for the parameters;

selecting, by the vehicle controller, a set of values on the basis of the error measures; and

controlling, by the vehicle controller, the vehicle using the values of the selected set of values for the parameters.

2. The method according to claim 1 , wherein the set of values which produces the smallest error measure is selected.

3. The method according to claim 1 ,

wherein the sets of values are provided by programming during the manufacture of the vehicle or the controller.

4. The method according to claim 1 ,

wherein the test route is driven immediately following the manufacture of the vehicle and/or is a test route for product testing following the manufacture of the vehicle.

5. The method according to claim 1 ,

wherein the error measures are at least partially calculated during the execution of vehicle functions which are executed during the operation of the vehicle.

6. The method according to claim 1 ,

wherein the error measures are at least partially calculated by a number of error determination algorithms provided especially for this purpose.

7. The method according to claim 6 ,

wherein a part of the parameters is exclusively used in the error determination algorithms.

8. The method according to claim 1 ,

wherein the error measures are at least partially calculated by Kalman filters, particle filters, estimation methods or neural networks.

9. The method according to claim 1

wherein the operating variables are checked prior to the error calculation in an initial diagnosis.

10. The method according to claim 1 ,

wherein the selected set of values are selected by eliminating sets of values at intervals, wherein the set of values having the greatest error measure is eliminated in each of the intervals until the set of values which produces the smallest error measure is selected.

11. The method according to claim 1 ,

wherein the set of values which produces the lowest error measure is selected after a predefined time.

12. The method according to claim 1 , wherein the parameters are at least partially selected from the group consisting of:
